At Rakow in Poland was published the catechism of the Socinian doctrines in 1605.
A Socinian Bible was issued by Simon Budny in 1570 at Nieswiez, as he professed to find many faults in the version issued under the patronage of Radziwill; in 1597 appeared the Roman Catholic version of the Jesuit Wujek; and in 1632 the so-called Danzig Bible, which is in use among Protestants and is still the most frequently reprinted.
It is worthy of notice that this intercourse with Cromwell occurred when Baxter was summoned to London to assist in settling "the fundamentals of religion," and made the memorable declaration, in answer to the objection that what he had proposed as fundamental "might be subscribed by a Papist or Socinian," - "So much the better, and so much the fitter it is to be the matter of concord."
In 1693 he published four lectures on the Socinian controversy.
